HYDROCARBON-LAM P.

SPECIFICATION forming part of Letters Patent N 0. 700,47 5, dated May20, 1902.

' Application filed February 7, 1899. Serial No. 704,793. (110 model.) I

To LUZ whom, in may concern:

Be it known that I, THOMAS H. BLAIR, a citi-' zen of the United States,residing at North-- hero, in the county of Worcester andState ofMassachusetts, have invented a new and useful Hydrocarbon-Lamp, of whichthe following is a specification.

The aim of this invention is to, provide a newand improved hydrocarbon-lam p in which the parts shall be simply and convenientlyarranged, in which thesupply of oil orliquid shall be automaticallyregulated, and in which the oil and vapor can be quickly shut off andcontrolled when it is desired to extinguish the lamp.

To these ends myinvention consists of the combinations and devicesdescribed in this specification and illustrated in the accom-., panyingfour sheets of drawings, in which-f Figure 1 is a side View, partiallybroken away, showing the conneetionof two-lamps constructed according tomyinvention with an oil-tank. Fig. 2 is asectional view of my pre-.

ferred form of lamp. Fig. 3 is a plan view 1 of the perforatedburner-plate. Fig. 4 is a sectional view at right angles to Fig. lot thevaporizing-chamber. Fig. 5 is a plan View of the vaporizing-chamber.Fig. 6 is azview similar to Fig. 1, illustrating amodified form ofconstruction; and Fig. 7 is an enlarged detail view showing the positiveshut-01f valve in its closed position. I i

My improved lamp consists of a vaporizingchamber located above asuitable burner, in which chamber is placed a diaphragm'which connectsto a valve controlling the supply, so that the pressure generated in thevap'orizing-chamber will automatically regulate the; oil-supply. A'double-valve system is also provided in connection with suitable operat?ing means, so that when the lamp isextinguished the supply of vapor fromthe vaporizing-chamber to the burner. will be cutoff and simultaneouslythe supply of oil to the vaporizing-chamber will be positively stopped.f

- The invention also consists of certain improved details ofconstruction hereinafter rewill first describe the preferred form oflamp illustrated in the first two sheets of the drawings.

. 1O designates avaporizing-chamber, which I have shown made circular inform. In the top of this chamber is arranged a ledge 11,

and screwed into the top of the chamber is a perforated cap 12.

Arranged between the ledge 11 and the cap 12, is an asbestos packing anda diaphragm 13.

14:- designates a supply-pipe, and the same may have a suitable valve15. The supplypipe 14 is screwed into a suitable boss extending from thevaporizing-chamber. Extending from this boss is a feed-pipe'lG, which isbent around, as shown in Fig. 4, so as to be flexible. The end ofthefeed-pipeisfitted into the side of a small hollow cup orcylin der 17which has a valve-seat arranged on the top thereof. This cylinder 17isconnected by suitable straps 18 to the diaphragm 13,

so that the same will move up and down with the said diaphragm.

19 designates a square yoke which sur-' rounds the cylinder 17. .Theunder side of said yoke forms a valve and has a cushion20, .made out ofasbestos or other suitable materia'h'arranged to engagethe valve-seatformed 'onthe top of the supply-cylinder 17. -2lis preferably arrangedto project from said valve20'down through the valve-seat'formed ronltopof the cylinder 17, so as to prevent by movement of the diaphragm oroperating- ;handle any impurities clogging said valve. IQnthe lower sideof said yoke 19 is arranged another asbestos cushion, which forms avalve A pin 22. Said valve 22 is set to cooperate with the upper end ofa tube 23, which extends up into said chamber 10 to form a valve-seatand a trap to retain theoil in the chamber. This "is an advantageousconstruction in that a certain amount of oil will be trapped or held onthe bottom of the chamber up to the top of .the tube 23, so that a largesurface of the same will be exposed to the heat of the lamp.

Extending from the yoke 19 down through the tube 23 is a rod 24, thelower end of which is threaded into an operating-handle 25. Thisoperating -handle 25 is fitted into-tlielower end of the tube 23. Thelower end ot the tube loo - handle 25, as shown.

23 is fitted into a hub 27,. The handle and tube are kept in place bymeans of one or hub and said tube and which fit into an annular groovecut in the shank of the screw- By this means as the screw-handle isturned the rod 2t can be raised or lowered.

The tube 23 has small outlet-holes 28, which permit the vapor to passout into a suitable chamber for mixing the vapor and air, myconstruction having a base 29, which is secured to the hub27 by pins orbraces 30. The upper end of the base is provided with a perforated plate81, and the shoulder of the base 29 is provided with a suitable ring ofwiclting orabsorbent material 300, which may be filled with alcohol andlighted when it is desired to start the lamp into operation. A suitablemantle S2 is arranged between the bottom of the vaporizing-chamber andthe plate 31. I

A collar 33 may be held on the base 29 by suitable clips 34:, and thiscollar may support a chimney 3G and a porcelain cup 35. A shade 37 mayalso be arranged to protect the upper part of the lamp and can besecured to the vaporizing chamber by means of suit-able screws 38.

The operation is as follows: The lamp is started into operation bysaturating the wicking 2500 with alcohol and lightingthe same. At thesame time the screw-handle is operated to raise the valves 20 and 22from their seats. Oil will then pass up over the valveseat formed on topof the cylinder 17 and will drop onto the bottom of thevaporizing-chamber 10 and will there be converted into vapor, which willfill the chamber, and the excess passing under pressure down through thetube 23 will be forced out through the holes 28 up into the base 29. Asthe same rushes up into the burner outside the tube 23 air will be drawninto the bottom of the base and mixed with the Vapor, which mingledvapor and air will be ignited by the alcohol-flame and will burn abovethe plate 31. This will continue the heating and generating of vaporuntil the supply of alcohol will have burned out, when the lamp willcontinue in operation. This will render the mantle incandescent and willgive a brilliant light. When pressure is increased beyond a desirablepoint in the vaporizing-chamber 10, the diaphragm will be pushed upward.This will raise the cylinder 17 against the valve 20, and this actionwill automatically regulate the supply of oil to the vaporizing-chamberby shutting off the supply of oil when the desired pressure is obtainedand by opening to allow oil to enter the vaporizing-chamber when thepressure falls or by keeping the valve in such position that the supplywill be set to just feed the proper amount of oil to keep the pressuresubstantially constant. When it'is desired to extinguish the lamp, thescrew-handle 25 is seats. This action will simultaneously stop the 1supply of oil to the vaporizing-chamber and the supply of vapor to theburner.

The arrangement of cylinder 17 and flexible feedpipe 16 isa verydesirable one,bccause by this construction the oil is brought to a hightemperature before it is allowed to escape into the vaporizing-chamber,and the cylinder 17 thus forms a small reservoir ol heated oil, which isready for use the instant the diaphragm descends and allows the escapeof the same between the valve-seat and the valve 20; t

In Fig. 5 I have shown a modification. In this modification thesupply-pipe 16 is brought down under the vaporizing-chamber 10 and iscarried up into a valve-chamber40, formed on the inside of thevaporiziug-chamber. Fitting loosely in the valve-chamber 40 and hearingon a seat formed therein is a small Valve 41, which is arranged ontheend of a link 42, which link is connected to the rod 2t and is pivotedat its center to a bracket43.

The upper end of the rod 24.- in this construction is connected to thediaphragm. The lower end of the rod in this construction rests upon butis not connected with a taper plug 44., formed on the shank of thescrew-handle 25. The screw-handle in this modification is threaded intothe lower end of the tube 23, and the shank of the screw-handle isformed with the taper plug at, which cooperates with acorrespondinglytapered seat through which the holes 28 are bored, sothat when the tapered plug 44 is screwed up it will out off .the supplyof oil to the openings 28. In this construction pressure generated inthe vaporizing-chamber will by pressure on the diaphragm operate thevalve 41 to automatically regulate the supply of oil. NVhen it isdesired to extinguish the lamp, the screwhandle 25 is turned. This willpush up on the rod 24 and will force the valve 41 to its seat, thusclosing the supply of oil. At the same time the plug 4st will come toits seat and will thus close the opening 28 and will thus stop thesupplyofvapor to the burnerand extinguish the lamp. Thus a double valveis formed by this construction-one valve, which automatically regulatesthe supply of oil and which may be positively closed, and a secondvalve, which maybe simultaneously positively closed with the first valveto stop the supply of vapor to the burner.

The details herein described may be varied from by skilled and artisticmechanics to form a table-lamp or one to be suspended from the ceilingwithout departing from the scope of my invention as expressedin theclaims. In modifying the construction for asuspensionlamp the feed-pipe16 can be carried up around through the cap 12, to which cap asupply-pipe extending from the ceiling can be screwed. The constructionshown, however, is preferred, as with the same the cap 12 can beunscrewed toget'at the workingparts in the chamber Without interferingwith the su pply pipe=or lamp.

, In some casesanextra'number of vapor pipes can be carried'fromthe'vaporizing" chamber to othermu'rners, and thus form a.

chandelier. Y
